Customer Question

I have a 2009 sea Ray with 496 mag engine. If I run over 3500 rpm for anytime engine temp is around 160 but when I cut back to idle alarm will go off and it goes into limp mode put it back into neutral and let run a while it will let me go again and everything is fine until I bring it back to idle. Can run all day at 3000 rpm and then go to idle with no problem

Hello my name is ***** ***** am I speaking with?

Is the alarm a solid tone or a series of beeps?

When was the last time the cooling system was serviced with a new impeller?

A solid tone and engine goes to limp mode pull out of gear and alarm will quit but you have to let run a while before you can put in gear and go. Only replaced raw water pump have never changed antifreeze pump
